Recently I have encountered with the same problem. Tell me, please, have you fixed it?

Show please what kind of errors do you receive?

Hi, we use online receipt validation, server response contain this info for example: environment = Sandbox; "latest_receipt" = "<base64 encoded receipt>"; "latest_receipt_info" = ( { **"expires_date" = "2021-04-01 08:11:41 Etc/GMT";** "expires_date_ms" = 1617264701000; "expires_date_pst" = "2021-04-01 01:11:41 America/Los_Angeles"; "is_in_intro_offer_period" = false; "is_trial_period" = false; "original_purchase_date" = "2021-04-01 08:06:43 Etc/GMT"; "original_purchase_date_ms" = 1617264403000; "original_purchase_date_pst" = "2021-04-01 01:06:43 America/Los_Angeles"; "original_transaction_id" = 1000000796251683; "product_id" = "<some product id>"; "purchase_date" = "2021-04-01 08:06:41 Etc/GMT"; "purchase_date_ms" = 1617264401000; "purchase_date_pst" = "2021-04-01 01:06:41 America/Los_Angeles"; quantity = 1; "subscription_group_identifier" = 20744130; "transaction_id" = 1000000796251683; "web_order_line_item_id" = 1000000061338245; } ); **"pending_renewal_info" = ( { "auto_renew_product_id" = "<some product id>"; "auto_renew_status" = 1; "original_transaction_id" = 1000000796251683; "product_id" = "<some product id>"; }** ); receipt = { "adam_id" = 0; "app_item_id" = 0; "application_version" = "4.0"; "bundle_id" = "<some bundle id>"; "download_id" = 0; "in_app" = ( { "expires_date" = "2021-04-01 08:11:41 Etc/GMT"; "expires_date_ms" = 1617264701000; "expires_date_pst" = "2021-04-01 01:11:41 America/Los_Angeles"; "is_in_intro_offer_period" = false; "is_trial_period" = false; "original_purchase_date" = "2021-04-01 08:06:43 Etc/GMT"; "original_purchase_date_ms" = 1617264403000; "original_purchase_date_pst" = "2021-04-01 01:06:43 America/Los_Angeles"; "original_transaction_id" = 1000000796251683; "product_id" = "<some product id>"; "purchase_date" = "2021-04-01 08:06:41 Etc/GMT"; "purchase_date_ms" = 1617264401000; "purchase_date_pst" = "2021-04-01 01:06:41 America/Los_Angeles"; quantity = 1; "transaction_id" = 1000000796251683; "web_order_line_item_id" = 1000000061338245; } ); "original_application_version" = "1.0"; "original_purchase_date" = "2013-08-01 07:00:00 Etc/GMT"; "original_purchase_date_ms" = 1375340400000; "original_purchase_date_pst" = "2013-08-01 00:00:00 America/Los_Angeles"; "receipt_creation_date" = "2021-04-01 08:06:43 Etc/GMT"; "receipt_creation_date_ms" = 1617264403000; "receipt_creation_date_pst" = "2021-04-01 01:06:43 America/Los_Angeles"; "receipt_type" = ProductionSandbox; "request_date" = "2021-04-01 08:06:46 Etc/GMT"; "request_date_ms" = 1617264406754; "request_date_pst" = "2021-04-01 01:06:46 America/Los_Angeles"; "version_external_identifier" = 0; }; status = 0; }

at first you have to symbolicate your crash log

Hi, unfortunately, I did not solve this problem.

Hi, every relaunch/rebuild reinstalls app with new generated guid in the intall path of the app, that's why app can not find the file in app documents directory.

no :(

Did reviewers provide some crash-report to research?

Так пусть определенный круг скинется и будет тебе аккаунт с сертификатом для подписи.

Try to find out crashlog in Privacy & Security -> Analytics & Improvements-> Analytics Data with name pattern "YourAppName-date of crash-time of crash.ips"(also maybe *.ips.synced)

First of all app should read receipt data, validate it by Apple certificate, decode data to get purchases and another info to configure/lock/unlock some functionality, by getting receipt data during debug your app will be promted to enter login and pwd of sandbox account. You should try to purchase with sandbox account.

Can check it

You can restore your iphone to ios15.7 by downloading ios15.7 firmware and restore from Finder. Before doing it backup your iphone. Download firmware from here https://ipsw.me/

It works after 10 min of inactivity, maybe some problems with bluetooth. I had to turn off then turn on bluetooth to link them, without this manipulation they don't want to link.

I also recomed you to buy m1-macbook or m1-macmini, as for me m1-macmini is the perfect decision(with at least 16gb ram and 512 gb ssd), intel-macbook is the past epoch, Apple will not support intel-macbooks in a few years.
